Algebra | A mathematical language of symbols including variables. |
Algebraic expression | A combination of variables numbers and at least one operation. |
Associative property | The way in which numbers are grouped does not change the sum or product. |
Base | In a power, the number used used as a factor. In 10 3 the base is 10 that is 10 3 =10*10*10. |
Coefficient | The numerical factor of a term that contains a variable |
Commutative property | The order in which numbers are added or multiplied does not change the sum or product. |
Constant | A term without a variable. |
Defining the variable | Choosing a variable and deciding what the variable represents. |
Distributive property | |

To multiply a sum by a number, multiply each addend by the number outside the parenthesis. | |
Expressions that have the same value regardless of the values of the variables. | |
To find the value of an algebraic expression by replacing variables with numbers. | |
In a power, the number that tells how many times the base is used as a factor. 5 3 the exponent is 3. That is, 5 3 =5x5x5. | |
The process of writing numeric or algebraic expressions as a product of there factors. | |
The greatest of the common factors of two or more numbers. | |

The greatest of the common factors of two or more numbers. | |
Properties that state that the sum of any number and 0 equals the number and that the product of any number and 1 equals the number. | |
The smallest whole number greater tha zero that is a common multiple of each of two or more numbers. | |
Terms that contain the same variables to the same power. | |
A combination of numbers and operations. | |
The rules that tell which operation to perform first when more than one oppration is used. | |
A number expressed using an exponent. The power 3 2 is read three to the second or three squared. | |
The status of an expression when it has no like terms and no parenthesis. | |
Each part of an algebraic expression separated by a plus or minus sign. | |
A symbol usually a letter used to represent a number. |
